4. If the system-board tray is installed in a chassis, remove it (see "Removing a
system-board tray from a 2U chassis" on page 26 or "Removing a
system-board tray from a 3U chassis" on page 27).
5. If an expansion enclosure is installed on the system-board tray, remove it (see
"Removing an expansion enclosure" on page 29); otherwise, remove the
system-board tray cover (see "Removing the system-board tray cover" on page
28).
6. Locate the DIMM connectors (see "System-board connectors" on page 14).
Determine the connectors into which you will install the DIMMs.
Attention: To avoid breaking the DIMM retaining clips or damaging the
DIMM connectors, open and close the clips gently.
7. Open the retaining clips and, if necessary, remove any existing DIMM.
8. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the system-board tray; then, remove the DIMM from the
package.
9. Turn the DIMM so that the DIMM keys align correctly with the connector on the
system board.
10. Insert the DIMM into the connector by aligning the edges of the DIMM with the
slots at the ends of the DIMM connector. Firmly press the DIMM straight down
into the connector by applying pressure on both ends of the DIMM
simultaneously. The retaining clips snap into the locked position when the
DIMM is firmly seated in the connector. If there is a gap between the DIMM
and the retaining clips, the DIMM has not been correctly installed. Open the
retaining clips, remove the DIMM, and then reinsert it.
If you have other devices to install or remove, do so now. Otherwise, go to
"Completing the installation" on page 42.
